• Publication in June in Cancers journal of long-term safety and efficacy data in multiple hard-to-treat superficial cancers, with an overall response rate of almost 100% in treated lesions, no moderate or severe long-term toxicities noted, and a 2-year local recurrence-free survival was estimated at 77%

JERUSALEM, Aug. 14, 2024 (GLOBE NEWSWIRE) -- Alpha Tau Medical Ltd. ("Alpha Tau", or the “Company”) (NASDAQ: DRTS, DRTSW), the developer of the innovative alpha-radiation cancer therapy Alpha DaRT^®, reported second quarter 2024 financial results and provided a corporate update.

"While we continue to advance our ReSTART U.S. multicenter pivotal trial in recurrent cutaneous squamous cell carcinoma, the overwhelming interest from clinicians and the broader community in our ongoing internal organ trials has been fantastic,” stated Alpha Tau CEO Uzi Sofer. "We are fortunate to see such strong clinician demand for participation in clinical trials, at a time when we expect meaningful data generation, in particular with continued progress in our clinical trials in pancreatic cancer outside the U.S. as well as regulatory progress on similar trials in the U.S. We also continue to prepare for potential future product launches by advancing our commercial planning activities and solidifying our supply chain, as we have secured approvals for our new manufacturing plant in Hudson, New Hampshire and commenced renovation of the facility for our needs. Alpha Tau expects to remain adequately capitalized to support all of these programs over the coming years," he concluded.

Recent Corporate Highlights:

• In June, Alpha Tau announced the publication of “Extended Follow-Up Outcomes from Pooled Prospective Studies Evaluating Efficacy of Interstitial Alpha Radionuclide Treatment for Skin and Head and Neck Cancers” in the journal Cancers. The pooled analysis included data from 4 international clinical trials spanning an array of hard-to-treat indications including skin, head & neck, and oral cavity. Initial response data demonstrated an overall response rate of almost 100% in treated lesions and a complete response rate of 89%. With follow-up as long as 51 months (median follow-up of 14 months), no moderate or severe long-term toxicities were noted, and 2-year local recurrence-free survival was estimated at 77%.

About Alpha DaRT^®

Alpha DaRT (Diffusing Alpha-emitters Radiation Therapy) is designed to enable highly potent and conformal alpha-irradiation of solid tumors by intratumoral delivery of radium-224 impregnated sources. When the radium decays, its short-lived daughters are released from the sources and disperse while emitting high-energy alpha particles with the goal of destroying the tumor. Since the alpha-emitting atoms diffuse only a short distance, Alpha DaRT aims to mainly affect the tumor, and to spare the healthy tissue around it.

About Alpha Tau Medical Ltd.

Founded in 2016, Alpha Tau is an Israeli oncology therapeutics company that focuses on research, development, and potential commercialization of the Alpha DaRT for the treatment of solid tumors. The technology was initially developed by Prof. Itzhak Kelson and Prof. Yona Keisari from Tel Aviv University.
